Hidden cameras in Airbnbs. GPS trackers on rental cars. Fake WiFi at the hotel. SentryRF turns your Android phone into a professional room scanner — using on-device AI to find spy cameras, planted trackers, rogue networks, and surveillance devices — all with your phone's built-in sensors.
These are the threats travelers face — and exactly how SentryRF detects them.
A pinhole camera inside a smoke detector, alarm clock, TV, or wall fixture. Connected to the property's WiFi or recording to a hidden memory card. More common than you think — and invisible to the naked eye.
A magnetic tracker attached under the wheel well, inside the bumper, or behind a panel. Could be from a rental company, a stalker, or a thief tracking your route to your hotel.
A rogue access point broadcasting the same network name as the real one. Anyone who connects has their traffic intercepted — passwords, banking, emails, everything.
An AirTag, Tile, or SmartTag dropped into your bag at the airport, a conference, or a bar. Someone now knows every hotel, restaurant, and location you visit.
A drone circling your villa, resort, or private pool. Without Remote ID decoding, you'd never know who's flying it or where the operator is standing.
Someone wearing Ray-Ban Meta or Snap Spectacles — recording video of you and your family without anyone knowing.
Open SentryRF when you check in. Tap Scan to sweep for nearby trackers, hidden cameras on WiFi, and suspicious Bluetooth devices.
Use Physical Sweep mode. Walk slowly around the room — the magnetometer, microphone, and light sensor detect hidden electronics, ultrasonic emissions, and infrared LEDs.
Before connecting, SentryRF compares all networks with the same name. SentryRF compares all networks with the same name, checks for karma attacks and known beacons, and monitors your connection for DNS hijacking and deauth floods.
Use Vehicle Check mode before and after trips. Walk around the car once — SentryRF flags any new tracker that appeared while you were inside.
